My car takes a LONG time to warm-up...

i drove 45 minutes last night and my temp gauge still wasnt at the normal level. if i turn my heater on, the needle slowly goes back down and my heater blows colder air (its never warm air in the first place)

any idea whats wrong?

i like my car

Sounds like the thermostat is stuck open..be thankful it's open...when it gets stuck open it takes forever to warm up, if it gets stuck closed your car over-heats. I'd say just buy a new one anyway, they're cheap and should be replaced if you don't know the last time it was done;/ GL!

When I heated my home with oil, I used an average of 800 gallons a year. I have found that I can keep comfortably warm for an entire winter with slightly over half that quantity of beer.

If its stuck open, the cars water pump circulates freezing cold water at full flow. Normally, the thermostat holds the water in the engine long enough for the engine to begin heating the water. Once the water hits a certain temperature, the thermostat opens. If it cant hold onto the water long enough to heat it up, the little bit of warmth it gets going through at full flow gets lost immediately in the radiator.

Replace the 'stat.

I have a harder problem for you guys. It -20, -25 degrees here (Canada,QC). When i race my car 15 seconds (5-7000rpm), my temp gauge drop to 1/4. Race it 30 second = 1/5. The heater blower is colder than the normal temperature...
Thermostat= New
Radiator= New

One things i could possibily linked to this problem but not sure and didn't know how to fix it:
it always takes the air from outside (-25 degrees) to try to warm the inside of the car.

WTF is going on with my car ?!??

Maybe because the temps are at the extreme end and the car just doesnt like it? There are reasons why truckers block off portions of the radiator in xtreme temps.

yeah man just these past few weeks my temp gauge moves maybe a quarter inch in this weather. although it does go up when the car just idles. was talking to my dad and he said the t stat is prolly stuck open. and at this point the heat is basically non exsistent and what ever warmth i can get it has to be put on the highest blowing setting wich is 4. the other ones dont work. new heater core ? or a fuse ? im sure its been addressed before but i only have 526 posts so im still a newb and dont wanna search lol !. god damn im praying for warm weather to fix all this shit. it seems this cold weather has been taking a toll on my beast.

im back.......

well a stuck open thermostat would only affect length of time it takes for ur car to warm up...thats it....once it is warm up (normal op) ur t always stays open(natural function)...
and about ur blowing settings, maybe u have a bad blower motor

Did u mix the proper amount of coolant with water(50/50...winter i put maybe 60/40; 60 being colant)...*** if u got a lot more water than coolant, water got a higher frezzing point than coolant...i unno maybe thats it....or maybe u got a bad cts

the blower problem is the resistor. The intermediate speeds blew out leaving only the full voltage path.

You guys missed the part of bleeding the cooling system after installing the damn t-stat. 10mm screw next to the t-stat housing. Remember, air pocket could cause that too. check your coolant temp sensor and switch also. While your at it, flush your cooling system too. Helps you take corrosion and sludge out of your cooling system. Report back and let us know what happens.

Where is located the bleeding screw? Is it the same as drain plug (Chilton), just behind the exhaust manifold ? Cause this scew is lower than the thermostat housing...

Help me out
